Well I guess my list is as follows:
-Bonanza pilots (don't spill fuel on my wing!)
-Fueling the center tank on an Aerostar
-Doing Dry lavs
-A certain base pilot that loves to watch us move planes in and out of the hangar....just in case we end up hitting something.
-Pilots who are ###### bags
-When 1400 hits, I have a half hour left, but now second shift is on the clock. They usually take their good old time in "getting ready"...by chatting, eating, and lounging inside while the 1st shift guys are parking airplanes. Oh, and none of them have a radio on even though there are plenty available. So if we need assistance and all the other 1st guys are tied up...you're by yourself.
-Management, once again. We have two locations at this airport, the FBO and MX. We (the FBO) usually get the shaft on everything.
-Overwinging a certain Corporate Flight Department's Citation V. They come in everyday almost. It starts with M and ends with ards.
-Washing airplanes. I absolutely hate doing this because it's overly time consuming, and I would rather be out on the line than couped up in the hangar.
-Low Leader pilots who are complete #########s and complain about everything.
-A certain airline ground crew that will flip out if their plane isn't fueled 30 minutes prior to departure so they can go back to their office and watch TV.
-The fact that whenever we get food or sit down to eat...stuff starts happening.
-Piaggio P180...it's single point, that's great and all...but it seems like you could overwing it faster.
-Pilots who want their plane moved 20 ft closer to do the door.
And pretty much everything that everyone else said.
